How do you put full stacks of items in creative mode in the Windows 10 edition of minecraft?

This is already done for you. What confuses most people is that the 10 inventory slots that are always available only show 1 of the item that you are holding, no matter the amount that you actually have.

So, so Items are already full stacks if they are gotten from the creative inventory.
